I am not certain that Jasper 6.1 was certified against Spectrum 10.2.
However – we generally see that error when the “password” field is wrong.
If you are using superuser as the user, please re-type the password to see if the error goes away.
Either way, though, you should upgrade to CABI 6.3 to ensure support for all the reports that come with 10.2.
There are likely features that 6.1 does not have that reports from 10.2 utilize.
